The 1980s and 1990s floods provided extensive rearing and spawning habitat, which aided high survival rates for their offspring. This enabled them to expand their range greatly and they have become a chief ecological and economic nuisance (Hansen, p2).
Asian carps have engulfed the Illinois and Mississippi River systems after having escaped from aquaculture in the Deep South and as they have moved northward through.
